In the framework of the approved decision of Tender Commission of Russian Science together with the State Scientific Centre of Timber Processing Complex there has been started a research work “The research and development of technology of waste treatment of timber processing…”. The research will result not only in developing an efficient briquetting technology but also in creating a unique equipment complex.
According to the assignment of Leningradslanets JSC., the specialists of EcoMashGeo are in the process of elaborating technological decisions for the briquetting factory with the capacity up to 600 000 tons shale screenings annually and identifying the possibility of using different organic and mineral binders which preserve the value of the basic material.
Experimental and balance smelting of iron-carbon-containing briquettes made from Belgorod hydro-ore and coke screenings was started at Kosaya Gora Iron Works. It is planned to substitute briquettes efficiently for up to 250 kg of traditional charge materials per ton of pig iron.
The metallurgists of the Philippines delivered iron-carbon-containing materials to the laboratory of EcoMashGeo. The specialists of EcoMashGeo are producing briquette samples of natural shape for blast furnace production from the materials received.
Leningradslanets JSC. supplied EcoMashGeo with the samples of fine fraction materials. EcoMashGeo produced industrial samples of full-size briquettes from these materials. The mechanical and hot strength of the briquettes allows using them in traditional industrial units along with lump ore.
There was completed the first stage of the briquetting project at Suraj Products Ltd. The decisions on equipment placement developed by EcoMashGeo and approved by the owner of Suraj Products Ltd. Yogesh Kumar Dalmia meet both the technological requirements of metallurgic briquette production and traditions of Feng Shui.
The specialists of EcoMashGeo were invited by the company ERDEMIR (Turkey) to visit the plant Eregly Iron and Steel Works. There was approved a programme on briquetting the stored and forming at ERDEMIR fine-fraction iron-carbon-containing wastes and materials.
Orenburgugol JSC. provided the wastes from which EcoMashGeo produced industrial samples of full-size briquettes and transferred them for further testing.
There are continued the works on developing the smelting technology in induction furnaces with iron-carbon-containing briquettes when smelting steel and pig iron.
On the base of the received materials and wastes the specialists of EcoMashGeo along with the specialists of MISA (Moscow Institute of Steel and Alloy) developed mathematical models of smelting in the blast furnaces of Chelyabinsk Metallurgic Plant JSC (MECHEL company) and Dnepropetrovsk Iron and Steel Works named after Petrovsky (Ukraine). The modeling showed the ability to use up to 500 kg of the briquettes per ton of pig iron by decreasing considerably the consumption of metallurgic coke, iron ore and fluxes.
The samples of shale screenings were delivered to the laboratory of EcoMashGeo. The shale is extracted by Leningradslanets JSC. nn the city of Slanets in Leningrad region.
The specialists of EcoMashGeo were invited by the company Zenith to visit the plant in the city Neunkirchen (Germany) and examine the products produced.
KUMBA Iron Ore Ltd. carried out a full-scale testing of metallurgic briquettes made by EcoMashGeo earlier from the wastes produced at the territory of South Africa. The results of hot and mechanical strength of the briquettes confirm the ability to use the briquettes made by EcoMashGeo in metallurgic units to substitute for traditional charge iron-carbon-containing materials.
The industrial briquette samples of actual size and shape produced in the framework of the approved joint work Programme of Chelyabinsk Metallurgic Plant JSC (MECHEL company) and EcoMashGeo were tested successfully. The mechanical and hot strength of the briquettes allows using them as a full-fledged substitute for iron-ore materials and metallurgic coke in the blast furnaces of Chelyabinsk Metallurgic Plant JSC (MECHEL company) up to 500kg briquettes per ton of pig iron.
